"Exception in thread "main" java.lang.NoSuchMethodError: main"

[wanshotheawesome]

What recording Programm are you using?

[jpbooster]

when i di javac HelloWorld it says that it cannot find the symbol and the arrow points at the dot between out and printIn

what should i do??

[olanahab]

@jpbooster I had the same problem. My mistake was I put a capital "i" instead of a lower case "L" which look exactly the same.

[Briffothe]

Holy crap I just made my first java program!

[bassmasteraek]

[l4zrvids]

[fmaddict07]

where can you download JDK for mac?

[r0cksztar]

@fmaddict07 you dont need the JDK for Mac. It should come with it integrated with Java in the system.



[MrNinestarkiller]

@fmaddict07 JDK is probably already in your Mac. It is located in /System/Library/Frameworks/Jav­aVM.framework/Versions/1.6.0/H­ome/

[TheKatt08]

[Bluewhale88888888888]

after i have made it and then put it in terminal, what do i do with it?

[dwarfgamer]

Wait, does JDK come pre-installed on Mac?

[anthropamorphic]

can you put the code in the description

[CaniohApps]

@anthropamorphic public class HelloWorld { public static void main(String[] args) { System.out.println("Holy mother poop, this is my OWN Java program!!"); }

}

[ilikemuffinsandovals]

[playing0with0fire13]

@dylad Me too

[anikaatje]

Was using 'Java a beginners guide' but got stuck in the beginning already.

This really helped me out big time!

[EmotionsRUseless]

WHAT JOKE IS THIS THIS IS NOT RIGHT U ARE WRONG !@#$%

[michaelcacovski]

Awesome video man, helped me out in my first day of class because our university somehow just overlooked the fact that some people use macs to program on lol

[screwyouXD]

Question, I use textedit, are there any settings I will have to change to get it to work because when I use it, I can,t get the format right

[brelsj]

Thanks for this... extremely helpful.

[luckii13charm]

i downloaded jedit and it keeps saying "error read-only file"

[smil8888]

you don't have to name it the same as the class is named, when you compile it it will automaticly be called "YourClassName".class

[gizmoguyar]

Hey man thanks for making these tutorials, I really appreciate it.

[LivingSkits]

You make a lot of errors when you write your code!

Does that program have a compiler built into it?

[Tomniso1]

how do i reinstall it after accidentaly deleting it

[King4Nothing3]

i got this error while compiling(javac) The system cannot find message text for message number 0x2331 in the message file for Application.

plz help

[tina763]

Thank very Much.

[midinerd]

cool man! got it to print out that line successfully in like 1 minute. thanks for getting me started :)

[beenox123]

i installed jdk and it still gives the error "'javac' is not a recognized as an internal or external command, batch file or operable program."

[IDOG321]

@beenox123 right click my computer and go to properties then advanced then enviroment variables. look for the variable Path. change the value by putting a semicolon then your path to javac(java compiler)

example: C:\Program Files (x86)\Java\jdk1.6.0_20\bin

[beenox123]

@IDOG321 10x

[IDOG321]

@beenox123 you're welcome? lol

[YUPjpn]

Nice vid, this helped a lot!!!

[YUPjpn]

When I type in cd 'Java Tutorials' it doesn't work! Please help me!!!

[TheDimensionsofMac]

@YUPjpn is that the folder? LISTEN TO HIS WORDS

[macheads101]

@ishiidawg240 to do it go into the terminal/command line

enter the one command:

sudo apt-get install java

this may not work but you can also google it.

[ishiidawg240]

[mattguy1249]

nice but when I do the 'javac' bit it says:

"javac is not recognized as an internal or external program command, operable program or batch file."

do you know what to do?

[nathan8BIT]

@mattguy1249 you need to set the path variable

[joeboby9]
